Title: Improvements in machines for treating rubber and similar material
IPC: B29B7/12
Filed: 1926-06-02
Abstract: 273,455. Lewis, R. C., and Farrel Foundry & Machine Co. June 2, 1926. Feeding-devices.-The opening in the charging- stack of a. machine for treating rubber and similar materials is closed by a plunger, the underside of which conforms to and forms part of the internal wall of the chamber, and which is adapted to be slid into and out of the closed position, by means of a member mounted adjacent the stack for parallel movement with the plunger, and which is operated preferably by means of fluid-pressure. The slidable discharge opening is operated also by fluid-pressure. The invention is particularly applicable to machines for mixing, masticating, working or kneading rubber. As shown in Fig. 2, a hollow plunger 51 provided with a lower face 52 curved to conform to the shape of the mixing-chamber is slidably located in a charging-stack communicating with a hopper 46 and is provided with jackets 55, 56, which may be supplied with cooling fluid by pipes passing downwardly through the plunger. Operation of the plunger is effected by a piston 67, working in a cylinder 66 adapted to be supplied with fluid under pressure by pipes 71, 72 and acting through a rack 69 on a pinion 70 mounted on a shaft 64 carrying also a pair of pinions engaging racks provided on the rear face of the plunger. Inward movement of the plunger is limited by a stop 57 thereon which slides in a slot in the charging stack, and in the closed position the plunger may be locked by bolts 75, 76, Fig. 3, located in chambers 77, 78 to which fluid-pressure may be supplied by pipes 79, 80 from a pipe 81 which also supplies the upper end of the cylinder 66 through the pipe 71. By this means, the bolts are withdrawn when fluid under pressure is supplied to the cylinder 66 to raise the plunger. The discharge opening 22, the side walls of which are substantially normal to the internal surface of the mixing-chamber, is adapted to be closed by a closely fitting member 25, which is adapted to slide horizontally on bevelled bearing plates 30, 31 located in recesses 28, 29 in downward extensions 26, 27 integral with the mixing-chamber. The plates 30, 31 are adapted to be adjusted to take up wear by means of set screws 35, Fig. 4, and a screw 36. To the underside of the member 25 is secured a cylinder 39 adapted to be supplied with fluid under pressure by pipes 43, 44 and having therein a piston 40, the rod 41 of which is fixed at 42. With this arrangement, when fluid under pressure is supplied to the cylinder, the movement of the latter operates the member 25. Fluid-pressure for operating the cylinders &c. is supplied by an oil pump mounted on the base of the machine.

Abstract: 130,813. Pessell, R. C. Aug. 29, 1918. Lever and linkage platform load-handling machines and appliances; actuated from travelling wheels through eccentric toothed gearing or chain gearing.-The platform of a truck or trolly for conveying goods to a railway van, workshop bench, &c., is raised or lowered by the movement of the truck. The platform d, Fig. 2, is pivotally mounted on cross.bars c which connect the cranked axles b, b<1> of the wheels a. When the load is to be raised, pins h are passed through one of a series of holes in each wheel a and through a hole in each crank-arm b<1>. Further movement of the truck results in raising the load. When heavy loads are to be raised, the crossbars c supporting the platform d, Fig. 3, are connected to a double gear l which meshes with pinions i, j on the axle b. The gear l is pivotally mounted in a bracket k which is pivotally mounted on the axle b. The pinion i and wheel a can be interlocked by a pin h. If it is desired to raise the platform to a greater height than is possible when it is connected directly to the axles, the cross-bars c are connected to an endless chain p, Fig. 5, passed round sprockets o, n, the latter of which is driven by the wheel a through the gears i, n' when the pin h is inserted.

Patent GB-1106432-A (GB)
Title: Improvements relating to graphite structures in nuclear reactors
Inventor: NETLEY PETER THOMAS
IPC: G21C1/12
Filed: 1965-04-02
Abstract: 1,106,432. Moderator structures. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. 22 March, 1966 [2 April, 1965], No. 14109/65. Addition to 1,021,452. Heading G6C. A graphite moderator structure of which those parts having a normal operating temperature above 325‹ C. employ a graphite with a linear thermal expansion coefficient greater in at least one direction than 4À5 x 10<SP>-6</SP>/‹C. (measured over the range - 196‹ to +20‹ C.) is characterized in that such graphite is moulded (as distinct from extruded) and has an isotropy ratio in respect of the, thermal expansion properties which is not more, and preferably less, than 1À2. The graphite preferably has a linear thermal expansion coefficient greater than 5À0 x 10<SP>-6</SP>/‹C. Dimensional change, even in the long term, is kept low by the thermal expansion coefficients contemplated and the isotropy requirement ensures that such change does not lead to undesirable internal stressing of the graphite. In such a moderator structure, graphite blocks may be arranged in horizontal layers, the blocks of each layer being stacked on the preceding layer with both the round bore channels 1 and the shallow grooves 2 aligned between one layer and the next. Coolant, such as CO 2 , passes down through both the channels and the grooves, subsequently reversing direction beneath the structure and passing up through fuel assemblies within the channels 1. Each fuel assembly comprises an outer graphite sleeve 3 within which is supported a cluster of fuel pins 4. An elastic restraint means embraces the structure and consequently any shrinkage of the blocks results in the channels 1 being displaced towards the axis of the structure to an extent which increases progressively towards/the periphery of the structure. However, by using for the blocks a graphite as specified above the displacement can be held within acceptable limits, and the graphite relieved of the danger of being cracked by excessive internal stresses, so that even the simple design illustrated becomes a practical proposition for large reactor cores subject to extremely high neutron doses. Since the blocks are moulded and in moulded graphite the crystallites tend to align themselves with their C-axes perpendicular to the direction of pressing, it will be in this pressing direction that, in the long term, any switch from shrinkage to growth will be more prevalent. It is therefore preferred that the moulded graphite blocks are arranged with the pressing direction parallel to the axis of the structure. This eliminates any need for the provision of gaps between lateral faces of the blocks to cover the possibility of a switch to growth leading ultimately to an increase over the original dimensions.
